Marcie Natale's Bio:
Marcie Natale graduated from Millersville University with a BS in
Biochemistry and she received her MBA in International
Business from Temple. Marcie began her career at Henkel
Corporate Research in the organic synthesis department
focusing on defoamers, associative thickeners, and emulsion
polymerization of green surfactants. In 2001 Marcie joined
Cognis to focus on technical marketing, with an emphasis on
green and sulfate free surfactants and additives for shampoos &
body care. In 2006, Marcie was recruited by Eastman Chemical
Company to lead development teams in the personal care
segment. She is currently the biocatalysis platform development
manager for Eastman. Eastman’s biocatalysis platform was
recognized in June 2009 by the EPA. Marcie is a recipient of the
2009 EPA Presidential Award for Green Chemistry in the
category of Greener Synthetic Pathways. She continues to
develop commercial products by using green chemistry
principles.
Abstract for “A Green Process for Innovative
Cosmetic Ingredients":
Natural ingredients have always been important in the cosmetics
market, while the demand for the use of green processes is
becoming more important to both formulators and consumers.
While some definitions are still being debated, “natural”
typically refers to the source of the raw materials, and “green”
refers to the processes used to convert starting materials to a
finished ingredient. The Twelve Principles of Green Chemistry,
originally published by Paul Anastas and John Warner, have
been widely adopted as agency and industry standards. The
Principles of Green Chemistry can be readily applied to the
manufacture of cosmetic ingredients, with a goal of achieving
maximum efficiency and minimal environmental impact. This
presentation will review developments in green chemistry
technology for producing innovative ingredients, with a focus on
a biocatalytic manufacturing process that was recognized in
2009 with a Presidential Green Chemistry Challenge Award.
Eastman’s green biocatalytic process has been used to
synthesize a variety of cosmetic esters via enzymatic
esterifications at mild temperatures. The esterifications are
driven to high conversion by removing the coproduct, usually
either water from esterification of an acid or a lower alcohol
from transesterification of an ester. The mild processing
conditions do not lead to formation of undesirable byproducts
that may contribute color or odor. The immobilized enzyme, such
as lipase, is easily removed by filtration. The specificity of the
enzymatic conversions and the relatively low reaction
temperatures minimize the formation of byproducts, increase
yield, and save energy. A variety of ingredients produced by this
process, and their performance benefits, will be discussed.
